Portage LakePortage Lake's wave absorber was the most recently completed, in the summer of 2003. A 400-foot cell with a width of 20-30 feet was constructed in the north jetty. The slope of the rock is 2H:1V with 2.5-5 ton armor stone, 500-1500 lb underlayer stone and 1-50 lb bedding stone. The wave absorber is open to wave interaction on both sides with a concrete walk on the top supported by H-Piles. The predominant wave direction, in deep water, is out of the south-southwest. The project depth is 18 feet. Recent Aerial Photo
